| Accounting Policies [Abstract] | |
| Seasonality | Seasonality Consumer travel expenditures have historically followed a seasonal pattern. Correspondingly, travel partner advertising investments, and therefore our revenue and operating profits, have also historically followed a seasonal pattern. Our financial performance tends to be seasonally highest in the second and third quarters of a given year, which includes the seasonal peak in consumer demand, including traveler accommodation stays, and travel experiences taken, compared to the first and fourth quarters, which represent seasonal low points. In addition, during the first half of the year, experience bookings typically exceed the amount of completed experiences, resulting in higher cash flow related to working capital, while during the second half of the year, particularly in the third quarter, this pattern reverses and cash flows from these transactions are typically negative . Other factors may also impact typical seasonal fluctuations, such as significant shifts in our business mix, adverse economic conditions, public health-related events, as well as other factors . |
| Basis of Presentation and Consolidation | Basis of Presentation and Consolidation The accompanying consolidated financial statements include Tripadvisor, our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. All inter-company accounts and transactions have been eliminated in consolidation. Additionally, certain prior period amounts may have been reclassified for comparability with the current period presentation, none of which were material. The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). We believe that the assumptions underlying our consolidated financial statements are reasonable. However, these consolidated financial statements do not present our future financial position, or the results of our future operations and cash flows. One of our subsidiaries that operates in China has variable interests in affiliated entities in China in order to comply with Chinese laws and regulations, which restrict foreign investment in internet content provision businesses. Although we do not own the capital stock of these Chinese affiliates, we consolidate their results as we are the primary beneficiary of the cash losses or profits of these variable interest affiliates and have the power to direct the activity of these affiliates. Our variable interest entities’ financial results were not material for all periods presented. Investments in entities in which we do not have a controlling financial interest are accounted for under the equity method, the fair value option, as available-for-sale securities, or at cost adjusted for observable price changes and impairments, as appropriate. |
| Accounting Estimates | Accounting Estimates We use estimates and assumptions in the preparation of our consolidated financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our consolidated financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our consolidated financial statements are within accounting for income taxes. Refer to our accounting policy for income taxes disclosed below and “Note 10: Income Taxes ” for information regarding our significant income tax estimates. |
| Revenue Recognition | Revenue Recognition We generate all our revenue from contracts with customers. We recognize revenue when we satisfy a performance obligation by transferring control of the promised services to a customer in an amount that reflects the consideration that we expect to receive in exchange for those services. When we act as an agent in the transaction, we recognize revenue for only our commission on the arrangement. We determine revenue recognition through the following steps: (1) Identification of the contract, or contracts, with a customer (2) Identification of the performance obligations in the contract (3) Determination of the transaction price (4) Allocation of the transaction price to the performance obligations in the contract (5) Recognition of revenue when, or as, we satisfy a performance obligation. At contract inception, we assess the services promised in our contracts with customers and identify a performance obligation for each promise to transfer to the customer a service (or bundle of services) that is distinct. To identify the performance obligations, we consider all of the services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. We have provided qualitative information about our performance obligations for our principal revenue streams discussed below. There was no significant revenue recognized in the years ended December 31, 2023, 2022 and 2021 related to performance obligations satisfied in prior periods, respectively. We have applied a practical expedient and do not disclose the value of unsatisfied performance obligations that have an original expected duration of less than one year. The Company expects to complete its performance obligations within one year from the initial transaction date. The value related to our remaining or partially satisfied performance obligations relates to subscription services that are satisfied over time or services that are recognized at a point in time, but not yet achieved. Our timing of services, invoicing and payments are discussed in more detail below and do not include a significant financing component. Our customer invoices are generally due 30 days from the time of invoicing. We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. Although the substantial majority of our contract costs have an amortization period of less than one year , we have determined contract costs arising from certain sales incentives have an amortization period in excess of one year given the high likelihood of contract renewal. Sales incentives are not paid upon renewal of these contracts and therefore are not commensurate with the initial sales incentive costs. As of December 31, 2023 and 2022, there was $ 3 million and $ 4 million, respectively, of unamortized contract costs in other long-term assets on our consolidated balance sheet. We amortize these contract costs on a straight-line basis over the estimated customer life, which is based on historical customer retention rates. Amortization expense recorded to selling and marketing expense on our consolidated statements of operations during each of the years ended December 31, 2023, 2022 and 2021, wa s $ 1 million. We assess such asset for impairment when events or circumstances indicate that the carrying amount may not be recoverabl e. No impairments were recognized during the years ended December 31, 2023, 2022 and 2021. The recognition of revenue may require the application of judgment related to the determination of the performance obligations and the timing of when the performance obligations are satisfied. The determination of our performance obligations does not require significant judgment given that we generally do not provide multiple services to a customer in a transaction, and the point in which control is transferred to the customer is readily determinable. In instances where we recognize revenue over time, we generally have either a subscription service that is recognized over time on a straight-line basis using the time-elapsed output method, or based on other output measures that provide a faithful depiction of the transfer of our services. When an estimate for cancellations is included in the transaction price, we base our estimate on historical cancellation rates and current trends. Taxes assessed by a government authority that are both imposed on and concurrent with a specific revenue–producing transaction, that are collected by us from a customer, are reported on a net basis, or in other words excluded from revenue on our consolidated financial statements. Practical Expedients and Exemptions • We expense costs to obtain a contract as incurred, such as sales incentives, when the amortization period would have been one year or less. • We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. The application of our revenue recognition policies and description of our principal activities, organized by reportable segment from which we generate our revenue, are presented below. Brand Tripadvisor Segment (formerly Tripadvisor Core Segment) Tripadvisor-branded Hotels Revenue. Our largest source of Brand Tripadvisor segment revenue is generated from click-based advertising on Tripadvisor-branded websites, which we refer to as our hotel meta (also referred to as hotel auction) revenue, which is primarily comprised of contextually-relevant booking links to our travel partners’ websites. Our click-based travel partners are predominantly online travel agencies, or OTAs, and hotels. Click-based advertising is generally priced on a cost-per-click, or “CPC” basis, with payments from travel partners determined by the number of travelers who click on a link multiplied by the CPC rate for each specific click. CPC rates are determined in a dynamic, competitive auction process, where the travel partner bids for rates and availability to be listed on our platform. When a CPC bid is submitted, the travel partner agrees to pay us the bid amount each time a traveler clicks on the link to that travel partner’s website. Bids can be submitted periodically – as often as daily – on a property-by-property basis. We record click-based advertising revenue as the click occurs and traveler leads are sent to the travel partner’s website as our performance obligation is fulfilled at that time. Click-based revenue is generally billed to our travel partners monthly, consistent with the timing of the service. We also generate revenue from our cost-per-acquisition, or “CPA” model, which consists of contextually-relevant booking links to our travel partners’ websites which are advertised on our platform. We earn a commission from our travel partners, based on a pre-determined contractual commission rate, for each traveler who clicks to and books a hotel reservation on the travel partner's website, which results in a traveler stay. CPA revenue is billable only upon the completion of each traveler’s stay resulting from a hotel reservation. The travel partners provide the service to the travelers and we act as an agent under GAAP. Our performance obligation is complete at the time of the hotel reservation booking, and the commission earned is recognized upon booking, as we have no post-booking service obligations. We recognize this revenue net of an estimate of the impact of cancellations, using historical cancellation rates and current trends. Contract assets are recognized at the time of booking for commissions that are billable upon the completion of a traveler's stay. CPA revenue is generally billed to our travel partners two months after traveler stays are completed. In addition, we offer business-to-business, or “B2B,” solutions to hotels, including subscription-based advertising to hotels, owners of B&Bs, and other specialty lodging properties. Our performance obligation is generally to enable subscribers to advertise their businesses on our platform, as well as to manage and promote their website URL, email address, phone number, special offers and other information related to their business. Subscription-based advertising services are predominantly sold for a flat fee for a contracted period of time of one year or less and revenue is recognized on a straight-line basis over the period of the subscription service as efforts are expended evenly throughout the contract period. Subscription-based advertising services are generally billed at the inception of the service. When prepayments are received, we recognize deferred revenue initially on our consolidated balance sheet for the amount of prepayment in excess of revenue recognized, until the performance obligation is satisfied. To a lesser extent, we offer travel partners the opportunity to advertise and promote their business through hotel sponsored placements on our platform. This service is generally priced on a CPC basis, with payments from travel partners determined by the number of travelers who click on the sponsored link multiplied by the CPC rate for each specific click. CPC rates for hotel sponsored placements that our travel partners pay are generally based on bids submitted as part of an auction by our travel partners or a pre-determined contractual CPC rate. The travel partner agrees to pay us the CPC rate amount each time a traveler clicks on a link to the travel partner’s website. We record this click-based advertising revenue as the click occurs and traveler leads are sent to the travel partner as our performance obligation is fulfilled at that time. Hotel sponsored placements revenue is generally billed to our travel partners monthly, consistent with the timing of the service. Media and Advertising Revenue. We offer travel partners the ability to promote their brands through display-based advertising, or sometimes referred to as “media advertising”, placements across our platform. Our display-based advertising clients are predominantly direct suppliers of hotels, airlines and cruises, as well as destination marketing organizations. We also sell display-based advertising to OTAs and other travel related businesses, as well as to advertisers from non-travel categories. Display-based advertising is sold predominantly on a cost per thousand impressions, or “CPM,” basis. The performance obligation in our display-based advertising arrangements is to display a number of advertising impressions on our platform and we recognize revenue for impressions as they are delivered. Services are generally billed monthly. We have applied the practical expedient to measure progress toward completion, as we have the right to invoice the customer in an amount that directly corresponds with the value to the customer of our performance to date, which is measured based on impressions delivered. Tripadvisor Experiences and Dining Revenue. We generate revenue from our experiences and restaurant offerings on Tripadvisor-branded websites and mobile apps. Tripadvisor receives intercompany (intersegment) revenue consisting of affiliate marketing commissions earned primarily from experience bookings and, to a lesser extent, restaurant reservation bookings, on Tripadvisor-branded websites and mobile apps, fulfilled by Viator and TheFork, respectively, which are eliminated on a consolidated basis. The performance obligations, timing of customer payments for our experiences and dining transactions, and methods of revenue recognition are consistent with the Viator and TheFork segments, as described below. In addition, Tripadvisor restaurant offerings, or B2B restaurant offerings, generate subscription fees for subscription-based advertising to our restaurant partners that allow restaurants to manage and promote their website URL, email address, phone number, special offers and other information related to their business, as well as access to certain online reservation management services, marketing analytic tools, and menu syndication services. As the performance obligation is to provide restaurants with access to these services over a subscription period, the subscription fee revenue is recognized over the subscription period on a straight-line basis as efforts are expended evenly throughout the contract period. Subscription-based advertising services are generally billed at the inception of the service. When prepayments are received, we recognize deferred revenue initially on our consolidated balance sheet for the amount of prepayment in excess of revenue recognized, until the performance obligation is satisfied. In addition, we offer restaurant partners the opportunity to advertise and promote their business through restaurant media advertising placements on our platform. This service is generally priced on a CPC basis, with payments from restaurant partners determined by the number of clicks by consumers on the sponsored link multiplied by the CPC rate for each specific click. CPC rates for media advertising placements agreed to by our restaurant partners are based on a pre-determined contractual rate. We record this click-based advertising revenue as the click occurs and diner leads are sent to the restaurant partner as our performance obligation is fulfilled at that time. Click-based revenue is generally billed to our restaurant partners monthly, consistent with the timing of the service. Other Revenue. We also offer travelers alternative accommodation rentals, cruises, flights, and rental cars solutions on our platforms which complement our end-to-end travel experience. Our alternative accommodation rentals offering provides information and services that allow travelers to research and book vacation and short-term rental properties, including full homes, condominiums, villas, beach properties, cabins and cottages. Our alternative accommodation rentals offering primarily generates revenue by offering individual property owners and managers the ability to list their properties on our platform thereby connecting with travelers through a free-to-list, commission-based option. These properties are listed on our Tripadvisor-branded websites and mobile apps, and Tripadvisor's portfolio of travel media brands, including, www.flipkey.com, www.holidaylettings.co.uk, and www.niumba.com. We earn commissions associated with rental transactions through our free-to-list model from both the traveler and the property owner or manager. We provide post-booking services to the travelers, property owners and managers until the time the rental commences, which is the time the performance obligation is completed. Revenue from transaction fees is recognized at the time that the rental commences. Under GAAP, we act as an agent in the transactions, as we do not control any properties before the property owner provides the accommodation to the traveler and do not have inventory risk. We generally collect payment from the traveler at the time of booking, representing the amount due to the property owner or manager, as well as our commission. That portion of the payment representing our commission is recorded as deferred revenue on our consolidated balance sheet until revenue is recognized, and that portion of the payment representing the amount due to the property owner is recorded as a deferred merchant payable on our consolidated balance sheet until payment is made to the property owner after the completion of the rental. In addition, Other Revenue includes revenue generated from cruises, flights, and rental cars offerings on Tripadvisor-branded websites and mobile apps and Tripadvisor’s portfolio of brands, which primarily includes click-based advertising and display-based advertising revenue. The performance obligations, timing of customer payments for these offerings, and methods of revenue recognition are generally consistent with click-based advertising and display-based advertising revenue, as described above. Viator Segment We provide an online marketplace that allows travelers to research and book tours, activities and attractions in popular travel destinations across the globe through our Viator-branded platform, which includes website, mobile web, and mobile app. Through Viator, we also power traveler bookings of tours, activities and attractions on behalf of third-party distribution partner websites, including the Tripadvisor platform as well as many of the world’s major OTA’s, airlines, hotels, online and offline travel agencies, and other prominent content and eCommerce brands. We work with local tour, activity, and experience operators (“operators”) to provide travelers (“customers”) the ability to book tours, activities and attractions, or “experiences”, in destinations around the world. We generate commissions for each booking transaction we facilitate through our online reservation system, in exchange for certain activities, including the use of the Company’s booking platform, post-booking 24/7 customer support until the time of the experience and payment processing activities as the merchant of record, which is the completion of the performance obligation. These activities are not distinct from each other and are not separate performance obligations. As a result, the Company’s single performance obligation is to facilitate an experience, which is complete upon the time the experience occurs, and when revenue is recognized. We do not control the experience or have inventory risk before the operator provides the experience to our customer and therefore act as agent for substantially all of these transactions under GAAP. We collect payment from the customer prior to the experience occurring, which includes both our commission and the amount due to the operator. We record our commissions as deferred revenue on our consolidated balance sheet when payment is received, including amounts which are refundable subject to cancellation, until the experience occurs and revenue is recognized. The amount due to the operator is recorded as a deferred merchant payable on our consolidated balance sheet until completion of the experience, after which payment is remitted to the operator. To a much lesser extent, we earn commissions from third-party distribution partners, in this case, the customers, who display and promote on their websites the operator experiences available on our platform to generate bookings. In these transactions, we are not the merchant of record, and we generally invoice and receive commissions directly from third-party distribution partners. Our performance obligation is to allow the third-party distribution partners to display and promote on their website experiences offered by operators who utilize our platform, in exchange for which, we earn a commission when travelers book and complete an experience on the third-party distribution partner's website. We do not control the service or have inventory risk, and therefore act as an agent for these transactions under GAAP. We generally receive payment prior to the experience date for these transactions, and make payments to the operators after the experience is complete. Our performance obligation is complete, and revenue is recognized at the time of the booking, as we have no post-booking obligations to the customer. We recognize this revenue net of an estimate of the impact of cancellations, which is not material, using historical cancellation rates and current trends. Contract assets are recognized for commissions that are contractually billable contingent upon completion of the experience. TheFork Segment We provide information and services for consumers to research and book restaurants through our online restaurant reservations platform, TheFork. We primarily generate transaction fees (or per seated diner fees) that are paid by our restaurant customers for diners seated primarily from bookings through TheFork’s online reservation system. The transaction fee is recognized as revenue after the reservation is fulfilled, or as diners are seated by our restaurant customers. We invoice restaurants monthly for transaction fees. To a lesser extent, we also generate subscription fees for providing access to certain online reservation management services, marketing analytic tools, and menu syndication services. For these services, our performance obligation is to provide restaurants with access to these services over the subscription period, which generally is one-month, and we recognize revenue once our performance obligation is met and invoice restaurants monthly for these subscription services. Refer to “Note 18: Segment and Geographic Information ” for disaggregation of the Company’s revenue by major products and revenue sources. We have determined that disaggregating revenue into these categories achieves the disclosure objective under GAAP, which is to depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. |
| Deferred Revenue | Deferred Revenue Contract liabilities generally include payments received in advance of performance under the contract, and are realized as revenue as the performance obligation to the customer is satisfied, which we present as deferred revenue on our consolidated balance sheet. As of January 1, 2023, we had $ 44 million re corded as deferred revenue on our consolidated balance sheets, of which $ 41 million was recognized in revenue and $ 3 million was refunded due to cancellations by travelers during the year ended December 31, 2023. As of January 1, 2022, we had $ 36 million recorded as deferred revenue on our consolidated balance sheets, of which $ 34 million was recognized in revenue and $ 2 million was refunded due to cancellations by travelers during the year ended December 31, 2022. The difference between the opening and closing balances of our deferred revenue primarily results from the timing differences between when we receive customer payments and the time in which we satisfy our performance obligations. There were no significant changes in deferred revenue during the years ended December 31, 2023 and 2022 related to business combinations, impairments, cumulative catch-ups or other material adjustments. |
| Deferred Merchant Payables | Deferred Merchant Payables In our experience offerings and free-to-list alternative accommodation rental offerings, we receive payment from travelers at the time of booking or prior to the experience or property rental date, and we record these amounts, net of our commissions, on our consolidated balance sheet as deferred merchant payables. We pay the experience operators and rental property owners, after the travelers’ use. Therefore, we receive payment from the traveler prior to paying the experience operator or rental property owner and this operating cycle represents a working capital source or use of cash to us. Our deferred merchant payables balance was $ 237 million and $ 203 million at December 31, 2023 and 2022, respectively, on our consolidated balance sheets. The increase in our deferred merchant payables during the year ended December 31, 2023 was primarily due to increased consumer demand for our experience offerings. |
| Cost of Revenue | Cost of Revenue Cost of revenue consists of expenses that are directly related or closely correlated to revenue generation, including direct costs, such as credit card and other booking transaction payment fees, data center costs, ad serving fees, and other revenue generating costs. In addition, cost of revenue includes personnel and overhead expenses, including salaries, benefits, stock-based compensation and bonuses for certain customer support personnel who are directly involved in revenue generation. |
| Selling and Marketing | Selling and Marketing Selling and marketing expenses consist of direct costs, including traffic generation costs from paid online traffic acquisition costs (including SEM and other online traffic acquisition costs), syndication costs and affiliate marketing commissions, social media costs, brand advertising (including television and other offline advertising), promotions and public relations. In addition, our selling and marketing expenses consist of indirect costs such as personnel and overhead expenses, including salaries, commissions, benefits, stock-based compensation, and bonuses for sales, sales support, customer support and marketing employees. Advertising costs We incur advertising costs consisting of online advertising expense, including SEM and other online channels, and offline advertising costs, including television costs and other offline channels, to promote our brands. We expense the costs associated with communicating the advertisements in the period in which the advertisement takes place. We expense the production costs associated with advertisements in the period in which the advertisement first takes place. For the years ended December 31, 2023, 2022 and 2021, we recorded advertising expense of $ 706 million, $ 572 million, and $ 282 million, respectively, in selling and marketing expense on our consolidated statements of operations. We include prepaid advertising expenses in prepaid expenses and other current assets on our consolidated balance sheet, which was not material as of December 31, 2023 and 2022 . |
| Technology and Content | Technology and Content Technology and content expenses consist primarily of personnel and overhead expenses, including salaries and benefits, stock-based compensation expense, and bonuses for salaried employees and contractors engaged in the design, development, testing, content support, and maintenance of our platform. Other costs include licensing, maintenance, computer supplies, telecom, content translation and localization, and consulting costs. |
| General and Administrative | General and Administrative General and administrative expenses consist primarily of personnel and related overhead costs, including personnel engaged in leadership, finance, legal, and human resources, as well as stock-based compensation expense for those same personnel. General and administrative costs also include professional service fees and other fees including audit, legal, tax and accounting, and other operating costs including bad debt expense, non-income taxes, such as sales, use, digital services, and other non-income related taxes. |
| Stock-Based Compensation | Stock-Based Compensation Stock Options. Our employee stock options generally consist of service based awards. The exercise price is equal to the market price of the underlying shares of our common stock at the date of grant. In this regard, when granting stock option awards, our practice is to determine the applicable grant date and to specify that the exercise price shall be the closing price of our common stock on the date of grant. Our stock options generally have a term of ten years from the date of grant and typically vest equally over a four-year requisite service period. We amortize the grant-date fair value of our stock option grants as stock-based compensation expense over the vesting term on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. The estimated grant-date fair value of stock options is calculated using a Black-Scholes Merton option-pricing model (“Black-Scholes model”). The Black-Scholes model incorporates assumptions to fair value stock-based awards, which includes the risk-free rate of return, expected volatility, expected term, and expected dividend yield. Our risk-free interest rate is based on the yields currently available on zero-coupon U.S. Treasury issues, in effect at the time of the grant, whose remaining maturity period most closely approximates the stock option’s expected term assumption. Our expected volatility is calculated by equally weighting the historical volatility and implied volatility on our own common stock. Historical volatility is determined using actual daily price observations of our common stock price over a period equivalent to or approximate to the expected term of our stock option grants to date. Implied volatility represents the volatility calculated from the observed prices of our actively traded options on our common stock. When measuring implied volatility for a specific employee stock option grant, we generally rely on traded contracts with six month maturities or more and exercise prices approximately equal to the exercise price of the specific option grant. We estimate our expected term using historical exercise behavior and expected post-vest termination data. Our expected dividend yield is zero as we have not historically paid regular cash dividends on our common stock and do not expect to pay regular cash dividends for the foreseeable future. Restricted Stock Units. Restricted stock units (“RSUs”) are stock awards that are granted to employees entitling the holder to shares of our common stock as the award vests. RSUs are measured at fair value based on the quoted price of our common stock at the date of grant. We amortize the fair value of RSUs as stock-based compensation expense over the vesting term, which is typically over a four-year requisite service period on a straight-line basis, with the amount of compensation expense recognized at any date at least equaling the portion of the grant-date fair value of the award that is vested at that date. Performance-Based Awards. Performance-based stock options and RSUs vest upon achievement of certain company-based performance conditions and a requisite service period. On the date of grant, the fair value of a performance-based award is calculated using the same method as our service based stock options and RSUs as described above. We then assess whether it is probable that the individual performance targets would be achieved. If assessed as probable, compensation expense will be recorded for these awards over the estimated performance period. At each reporting period, we reassess the probability of achieving the performance targets and the performance period required to meet those targets. The estimation of whether the performance targets will be achieved and the performance period required to achieve the targets requires judgment, and to the extent actual results or updated estimates differ from our current estimates, the cumulative effect on current and prior periods of those changes will be recorded in the period estimates are revised, or the change in estimate will be applied prospectively depending on whether the change affects the estimate of total compensation cost to be recognized or merely affects the period over which compensation cost is to be recognized. The ultimate number of shares issued and the related compensation expense recognized will be based on a comparison of the final performance metrics to the specified targets. Market-Based Awards . We issue market-based performance RSUs, or MSUs, which vest upon achievement of specified levels of market conditions. The fair value of our MSUs is estimated at the date of grant using a Monte-Carlo simulation model. The probabilities of the actual number of market-based performance units expected to vest and resultant actual number of shares of common stock expected to be awarded are reflected in the grant date fair values; therefore, the compensation expense for these awards will be recognized assuming the requisite service period is rendered and are not adjusted based on the actual number of awards that ultimately vest. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive these awards, and subsequent events are not indicative of the reasonableness of our original estimates of fair value. The Company accounts for forfeitures in the period in which they occur, rather than estimating expected forfeitures. |
| Income Taxes | Income Taxes We record income taxes under the asset and liability method. Deferred tax assets and liabilities reflect our estimation of the future tax consequences of temporary differences between the carrying amounts of assets and liabilities for book and tax purposes. We determine deferred income taxes based on the differences in accounting methods and timing between financial statement and income tax reporting. Accordingly, we determine the deferred tax asset or liability for each temporary difference based on the enacted income tax rates expected to be in effect when we realize the underlying items of income and expense. We consider all relevant factors when assessing the likelihood of future realization of our deferred tax assets, including our recent earnings experience by jurisdiction, expectations of future taxable income, and the carryforward periods available to us for tax reporting purposes, as well as assessing available tax planning strategies. We may establish a valuation allowance to reduce deferred tax assets to the amount we believe is more likely than not to be realized. Due to inherent complexities arising from the nature of our businesses, future changes in income tax law, tax sharing agreements or variances between our actual and anticipated operating results, we make certain judgments and estimates. Therefore, actual income taxes could materially vary from these estimates. We classify deferred tax assets and liabilities as noncurrent on our consolidated balance sheet. We record liabilities to address uncertain tax positions we have taken in previously filed tax returns or that we expect to take in a future tax return. The determination for required liabilities is based upon an analysis of each individual tax position, taking into consideration whether it is more likely than not that our tax position, based on technical merits, will be sustained upon examination. |
| Cash And Cash Equivalents Restricted Cash And Marketable Securities | Cash, Cash Equivalents, Restricted Cash and Marketable Securities Our cash consists of available on demand bank deposits held in global financial institutions. Our cash equivalents generally consist of highly liquid investments, generally including money market funds, term deposits and marketable securities, with maturities of 90 days or less at the date of purchase. As of December 31, 2023 and 2022, our restricted cash, which primarily consists of legally restricted deposits and escrowed security deposits, was not material. We classify marketable securities as either short-term or long-term based on each instrument’s underlying contractual maturity date and as to whether and when we intend to sell a particular security prior to its maturity date. Marketable securities with maturities greater than 90 days at the date of purchase and 12 months or less remaining at the balance sheet date will be classified as short-term and marketable securities with maturities greater than 12 months from the balance sheet date will generally be classified as long-term. We classify marketable equity securities, limited by policy to money market funds and mutual funds, as either a cash equivalent, short-term or long-term based on the nature of each security and its availability for use in current operations. Our marketable securities are classified and accounted for as available-for-sale, and therefore are carried at fair value, with unrealized gains and losses, net of taxes, reported in accumulated other comprehensive income (loss) as a component of stockholders’ equity. Fair values are determined for each individual security in the investment portfolio. We determine the appropriate classification of our marketable securities at the time of purchase and reevaluate the designations at each balance sheet date. We invest in highly-rated securities, and our investment policy limits the amount of credit exposure to any one issuer, industry group and currency. The policy requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss and providing liquidity of investments sufficient to meet our operating and capital spending requirements and debt repayments. Realized gains and losses on the sale of marketable securities are determined by specific identification of each security’s cost basis. We may sell certain of our marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration, liquidity, and duration management. The weighted average maturity of our total invested cash shall not exceed 18 months , and no security shall have a final maturity date greater than three years , according to our investment policy. We continually review any available-for-sale securities to determine whether their fair value is below their carrying value. If the fair value of an available-for-sale security is below their carrying value, and either we intend to sell the security or we will be required to sell before recovery, then the difference between fair value and carrying value is recognized as a loss in other income (expense), net on our consolidated statements of operations. If we do not intend to sell and we will not be required to sell before recovery, then we analyze whether a portion of the unrealized loss is the result of a credit loss. When a portion of the unrealized loss is the result of a credit loss, we recognize an allowance for expected credit losses on our consolidated balance sheet and a corresponding loss in other income (expense), net on our consolidated statements of operations. Any portion of the unrealized loss on the available-for-sale securities that is not attributable to a credit loss would be recognized as an unrealized loss in accumulated other comprehensive income (loss) within our consolidated statements of changes in stockholders’ equity. The Company's investment portfolio at any point in time may contain various investments, including, in U.S. treasury and U.S. government agency securities, taxable and tax-exempt municipal notes, corporate notes and bonds, commercial paper, non-U.S. government agency securities, overnight demand deposits, and money market funds. The Company segments its portfolio based on the underlying risk profiles of the securities and has a zero loss expectation for U.S. treasury and U.S. government agency securities. The Company regularly reviews the securities in an unrealized loss position and evaluates the expected credit loss risk by considering factors such as historical experience, market data, issuer-specific factors, and current economic conditions. As of December 31, 2023 and 2022 , the Company had no available-for-sale securities. |
| Accounts Receivable and Allowance for Credit Losses | Accounts Receivable and Allowance for Expected Credit Losses Accounts receivable are recognized when the right to consideration becomes unconditional and are recorded net of an allowance for expected credit losses. We record accounts receivable at the invoiced amount. Our customer invoices are generally due 30 days from the time of invoicing. The Company uses the “expected credit loss” methodology, allowed under GAAP, in estimating its allowance for expected credit losses. We apply the “expected credit loss” methodology by first assessing our historical losses based on credit sales and then adding in an assessment of expected changes in the foreseeable future, whether positive or negative, to the Company’s ability to collect its outstanding accounts receivables, or the expectation for future losses. The Company develops its expectation for future losses by assessing the profiles of its customers using their historical payment patterns, any known changes to those customers’ ability to fulfill their payment obligations, and assessing broader economic conditions that may impact our customers’ ability to pay their obligations. Where appropriate, the Company performs this analysis using a portfolio approach. Portfolios comprise customers with similar characteristics and payment history, and we have concluded that the aggregation of these customers into various portfolios does not produce a result that is materially different from considering the affected customers individually. Customers are assigned internal credit ratings, as determined by the Company, based on our collection profiles. Customers whose outstanding obligations are less likely to experience a credit loss are assigned a higher internal credit rating, and those customers whose outstanding obligations are more likely to experience a credit loss are assigned a lower credit rating. We recognize a greater credit loss allowance on the accounts receivable due from those customers in the lower credit rating tranche, as determined by the Company. When the Company becomes aware of facts and circumstances affecting an individual customer, it also takes that specific customer information into account as part of its calculation of expected credit losses. The Company's exposure to credit losses may increase if our customers are adversely affected by changes in macroeconomic pressures or uncertainty associated with local or global economic recessions, or other customer-specific factors. The following table presents the changes in our allowance for expected credit losses for the periods presented:

Balance, end of period $ 21 $ 28 $ 28 |
| Property and Equipment | Property and Equipment We record property and equipment at cost, net of accumulated depreciation. We capitalize certain costs incurred during the application development stage related to the development of websites and internal use software when it is probable the project will be completed and the software will be used as intended. Capitalized costs include internal and external costs, if direct and incremental, and deemed by management to be significant. We expense costs related to the planning and post-implementation phases of website development as these costs are incurred. Maintenance and enhancement costs (including those costs in the post-implementation stages) are typically expensed as incurred, unless such costs relate to substantial upgrades and enhancements to the website or software resulting in added functionality, in which case the costs are capitalized. We compute depreciation using the straight-line method over the estimated useful lives of the assets, which is three to five years for computer equipment, capitalized website development, office furniture and other equipment. We depreciate leasehold improvements using the straight-line method, over the shorter of the estimated useful life of the improvement or the remaining term of the lease. |
| Leases | Leases We lease office space in a number of countries around the world, generally under non-cancelable operating lease agreements. Our corporate headquarters is our most significant office space lease and is accounted for as a finance lease under GAAP. The Company has also entered into data center and certain equipment leases, such as network equipment and other leases, which are not material to our consolidated financial statements. We determine whether a contract is or contains a lease at inception of a contract. We define a lease as a contract, or part of a contract, that conveys the right to control the use of identified property or equipment (an identified asset) for a period of time in exchange for consideration. Control over the use of the identified asset means that we have both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset. Our lease contracts contain both lease and non-lease components which we combine as a single component under our accounting policy by asset class, except for office space leases and certain other leases, such as colocation data center leases, which we account separately for the lease and non-lease components. For leases which the consideration in the contract is allocated to lease and non-lease components, we base it on each component’s relative standalone price. We determine standalone prices for the lease components based on the prices for which other lessors lease similar assets on a standalone basis. We determine standalone prices for the non-lease component based on the prices that third-party suppliers charge for services for similar assets on a standalone basis. If observable standalone prices are not readily available, we estimate the standalone prices based on other available observable information. However, for certain categories of equipment leases, such as network equipment and others, we account for the lease and non-lease components as a single lease component. Additionally, for certain equipment leases that have similar characteristics, we apply a portfolio approach to effectively account for operating lease right-of-use ROU assets and operating lease liabilities. The Company uses its estimated incremental borrowing rate as the discount rate in measuring the present value of our lease payments given the rate implicit in our leases is not typically readily determinable. Given we do not currently borrow on a collateralized basis, our incremental borrowing rate is estimated to approximate the interest rate in which the Company would expect to pay on a collateralized basis over a similar term and payments, and in economic environments where the leased asset is located. We use the portfolio approach to determine the discount rate for leases with similar characteristics or when the Company is reasonably certain that doing so would not materially affect the accounting for those leases to which a single discount rate is applied. We establish assets and liabilities for the estimated construction costs incurred under lease arrangements where we are considered the owner for accounting purposes only, or build-to-suit leases, to the extent we are involved in the construction of structural improvements or take construction risk prior to commencement of a lease. Upon occupancy of facilities under build-to-suit leases, we assess whether these arrangements qualify for sales recognition under the sale-leaseback accounting guidance under GAAP. If we continue to be the deemed owner, for accounting purposes, the facilities are accounted for as finance obligations. Finance Leases Finance lease ROU assets and finance lease liabilities are recognized at the lease commencement date or the date the lessor makes the leased asset available for use. Finance lease ROU assets are generally amortized on a straight-line basis over the lease term, and the carrying amount of finance lease liabilities are (1) accreted to reflect interest using the incremental borrowing rate if the rate implicit in the lease is not readily determinable; and (2) reduced to reflect lease payments made during the period. Amortization expense for finance lease ROU assets and interest accretion on finance lease liabilities are recorded to depreciation and interest expense, respectively, in our consolidated statement of operations. We lease approximately 280,000 square feet of office space for our corporate headquarters in Needham, Massachusetts. This lease has an expiration date of December 2030 , with an option to extend the lease term for two consecutive terms of five years each and is accounted for as a finance lease. Operating Leases Our office space leases, exclusive of our corporate headquarters, are operating leases, which we lease an aggregate of approximately 340,000 square feet at nearly 30 locations across North America, Europe and Asia Pacific, in cities such as New York, London, Sydney, Barcelona and Paris, primarily used as sales offices, subsidiary headquarters, and for international operations, pursuant to leases with various expiration dates, with the latest expiring in October 2034 . Operating lease ROU assets and liabilities are recognized at lease commencement date, or the date the lessor makes the leased asset available for use, based on the present value of lease payments over the lease term using the Company’s estimated incremental borrowing rate. ROU assets associated with operating leases comprise the initial lease liability, and are then adjusted for any prepaid or deferred rent payments, unamortized initial direct costs, and lease incentives received. Amortization expense for operating lease ROU assets and interest accretion on operating lease liabilities are recognized as a single operating lease cost in our consolidated statement of operations, which results effectively in recognition of rent expense on a straight-line basis over the lease period. The carrying amount of operating lease liabilities are (1) accreted to reflect interest using the incremental borrowing rate if the rate implicit in the lease is not readily determinable; and (2) reduced to reflect lease payments made during the period. We present the combination of both the amortization of operating lease ROU assets and the change in the operating lease liabilities in the same line item within the adjustments to reconcile net income (loss) to net cash provided by operating activities in our consolidated statement of cash flows. Lease incentives are recognized as reductions of rental expense on a straight-line basis over the term of the lease. Our operating leases generally include options to extend the lease terms for up to approximately 5 years and/or terminate the leases within 1 year , which we include in our lease term if we are reasonably certain to exercise these options. Payments under our operating leases are primarily fixed, however, certain of our operating lease agreements include rental payments which are adjusted periodically for inflation. We recognize these costs as variable lease costs on our consolidated statement of operations, which were not material during the years ended December 31, 2023, 2022 and 2021. In addition, our short-term lease costs were not material in any period presented. We also establish assets and liabilities at the present value of estimated future costs to return certain of our leased facilities to their original condition to satisfy any asset retirement obligations. Such assets are depreciated over the lease period into operating expense, and the recorded liabilities are accreted to the future value of the estimated restoration costs and are included in other long-term liabilities on our consolidated balance sheet. Our asset retirement obligations were not material as of both December 31, 2023 and 2022 . |
| Non-Marketable Equity Investments | Non-Marketable Equity Investments We account for non-marketable equity investments through which we exercise significant influence but do not have control over the investee under the equity method. Under this method, the investment, originally recorded at cost, is adjusted to recognize the Company’s share of net earnings or losses of the investment as they occur rather than as dividends or other distributions are received. Losses are limited to the extent of the Company’s investment in, advances to and commitments for the investee. In the event we are unable to obtain accurate financial information from the investee in a timely manner, we record our share of earnings or losses of such equity investment on a lag. Non-marketable equity investments that are not accounted for under the equity method and that do not have a readily determinable fair value are accounted for under the measurement alternative, allowed under GAAP. Under the measurement alternative, the carrying value is measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. Adjustments are determined primarily based on a market approach as of the transaction date. We classify our non-marketable equity investments as long-term assets on our consolidated balance sheet as those investments do not have stated contractual maturity dates. On a quarterly basis, we perform a qualitative assessment considering impairment indicators, if any, to evaluate whether these investments are impaired. Qualitative factors considered include industry and market conditions, financial performance, business prospects, and other relevant events and factors. When indicators of impairment exist, we prepare a quantitative assessment of the fair value of our equity investments, which may include using both the market and income approaches which require judgment and the use of estimates, including discount rates, investee revenues and costs, and available comparable market data of private and public companies, among others. When our assessment indicates that an impairment exists, we measure our non-marketable equity investments at fair value. Valuations of such privately-held companies are inherently complex and uncertain due to the lack of liquid market for such company’s securities. In addition, such investments are inherently risky in that such companies are typically at an early stage of development, may have no or limited revenues, may not be or may never become profitable, may not be able to secure additional funding or their technologies, services or products may not be successfully developed or introduced into the market. |
| Business Combinations | Business Combinations We account for acquired businesses using the acquisition method of accounting which requires that tangible assets and identifiable intangible assets acquired and assumed liabilities be recorded at the date of acquisition at their respective fair values. Any excess purchase price over the estimated fair value of the net tangible and intangible assets acquired is allocated to goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets may include but are not limited to future expected cash flows from customer and supplier relationships, acquired technology and trade names from a market participant perspective, useful lives and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Valuations are performed by management or third-party valuation specialists under management's supervision, where appropriate. Any changes to provisional amounts identified during the measurement period, calculated as if the accounting had been completed as of the acquisition date, are recognized in the consolidated financial statements in the reporting period in which the adjustment amounts are determined. |
| Goodwill and Intangible Assets | Goodwill and Intangible Assets Goodwill We assess goodwill, which is not amortized, for impairment annually during the fourth quarter, or more frequently, if events and circumstances indicate impairment may have occurred. We test goodwill for impairment at the reporting unit level. Goodwill is assigned to reporting units that are expected to benefit from the synergies of the business combination in which such goodwill was generated as of the acquisition date. We evaluate our reporting units when changes in our operating structure occur, and if necessary, reassign goodwill using a relative fair value allocation approach. Once goodwill has been allocated to the reporting units, it no longer retains its identification with a particular acquisition and becomes identified with the reporting unit in its entirety. Accordingly, the fair value of the reporting unit as a whole is available to support the recoverability of its goodwill. The Company has the option to qualitatively assess whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. In the evaluation of goodwill for impairment, we generally first perform a qualitative assessment to determine whether it is more likely than not (i.e., a likelihood of more than 50 %) that the estimated fair value of the reporting unit is less than the carrying amount. Periodically, we may choose to forgo the initial qualitative assessment and proceed directly to a quantitative analysis to assist in our annual evaluation. When assessing goodwill for impairment, our decision to perform a qualitative impairment assessment for an individual reporting unit in a given year is influenced by a number of factors, including, but not limited to the size of the reporting unit's goodwill, the significance of the excess of the reporting unit's estimated fair value over carrying value at the last quantitative assessment date, the amount of time in between quantitative fair value assessments from the date of acquisition or to establish an updated baseline quantitative analysis, and other performance and market indicators. During a qualitative assessment, if we determine that it is not more likely than not that the implied fair value of the goodwill is less than its carrying amount, no further testing is necessary. If, however, we determine that it is more likely than not that the implied fair value of the goodwill is less than its carrying amount, we then perform a quantitative assessment and compare the estimated fair value of the reporting unit to the carrying value. If the carrying value of a reporting unit exceeds its estimated fair value, the goodwill impairment is measured using the difference between the carrying value and the estimated fair value of the reporting unit; however, any loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit. In determining the estimated fair values of reporting units in a quantitative goodwill impairment test, we generally use a blend, of the following recognized valuation methods: the income approach (i.e. discounted cash flows model) and the market valuation approach, which we believe compensates for the inherent risks of using either model on a stand-alone basis. The discounted cash flows model indicates the fair value of the reporting units based on the present value of the cash flows that we expect the reporting units to generate in the future. Our significant estimates in the discounted cash flows model include: weighted average cost of capital; long-term rate of growth and profitability of the reporting unit; income tax rates and working capital effects. The market valuation approach indicates the fair value of the business based on a comparison to comparable publicly traded firms in similar lines of business and other precedent transactions. Our significant estimates in the market valuation approach model include identifying similar companies with comparable business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and/or income multiples in estimating the fair value of the reporting units. Valuations are performed by management or third-party valuation specialists under management's supervision, where appropriate. We believe that the estimated fair values assigned to our reporting units in impairment tests are based on reasonable assumptions that marketplace participants would use. However, such assumptions are inherently uncertain and actual results could differ from those estimates. The use of substantially different assumptions, estimates or judgments could trigger the need for an impairment charge, or materially increase or decrease the amount of any such impairment charge. During the Company's annual goodwill impairment test in the fourth quarter of 2023, a qualitative assessment was performed for all our reporting units, which are Brand Tripadvisor, Viator, and TheFork. We determined that it was not more likely than not that the fair value of any reporting unit was less than its carrying value, and, accordingly, no impairment charges were recorded during the year ended December 31, 2023. As part of the qualitative assessment for our annual 2023 goodwill impairment analysis of our reporting units, the factors that we considered included, but were not limited to: (a) changes in macroeconomic conditions in the overall economy and the specific markets in which we operate, (b) our ability to access capital, (c) changes in the online travel industry, (d) changes in the level of competition, (e) evaluation of current and future forecasted financial results of the reporting units, (f) comparison of our current financial performance to historical and budgeted results of the reporting units, (g) change in excess of the Company’s market capitalization over its book value, (h) changes in estimates, valuation inputs, and/or assumptions since the last quantitative analysis of the reporting units during the second quarter of 2022, (i) changes in the regulatory environment, (j) changes in strategic outlook or organizational structure and leadership of the reporting units; and (k) other relevant factors, and how these factors might impact specific performance in future periods. Intangible Assets Intangible assets with estimable useful lives, or definite-lived intangibles, are carried at cost and are amortized on a straight-line basis over their estimated useful lives and reviewed for impairment upon certain triggering events. We routinely review the remaining estimated useful lives of our definite-lived intangible assets. If we reduce the estimated useful life assumption, the remaining unamortized balance is amortized over the revised estimated useful life. Intangible assets that have indefinite lives are not amortized and are tested for impairment annually during the fourth quarter, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Similar to the qualitative assessment for goodwill, we may assess qualitative factors to determine if it is more likely than not that the implied fair value of the indefinite-lived intangible asset is less than its carrying amount. If we determine that it is not more likely than not that the implied fair value of the indefinite-lived intangible asset is less than its carrying amount, no further testing is necessary. If, however, we determine that it is more likely than not that the implied fair value of the indefinite-lived intangible asset is less than its carrying amount, we compare the implied fair value of the indefinite-lived asset with its carrying amount. If the carrying amount of an individual indefinite-lived intangible asset exceeds its implied fair value, the individual asset's carrying value is written down by an amount equal to such excess. The assessment of qualitative factors is optional and at our discretion. We may bypass the qualitative assessment for any indefinite-lived intangible asset in any period and resume performing the qualitative assessment in any subsequent period. We base our quantitative measurement of fair value of indefinite-lived intangible assets, which consist of Tripadvisor-brand trade name and trademarks, using the relief-from-royalty method. This method assumes that the trade name and trademarks have value to the extent that their owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate future revenues, the appropriate royalty rate and the weighted average cost of capital, however, such assumptions are inherently uncertain and actual results could differ from those estimates. During the Company's annual indefinite-lived intangible impairment test during the fourth quarter of 2023, a qualitative assessment was performed. As part of our qualitative assessment we considered, amongst other factors, the amount of excess fair value of our trade names and trademarks to the carrying value of those same assets, changes in estimates, and valuation input assumptions, since our previous quantitative analysis. After considering these factors and the impact that changes in such factors would have on the inputs used in our previous quantitative assessment, we determined that it was more likely than not that our indefinite-lived intangible assets were not impaired as of December 31, 2023. Impairment of Long-Lived Assets We periodically review the carrying amount of our definite-lived intangible assets and other long-term assets, including property and equipment, net and operating lease right-of-use assets, to determine whether current events or circumstances indicate that such carrying amounts may not be recoverable. Factors that would necessitate an impairment assessment include a significant adverse change in the extent or manner in which an asset is used, a significant adverse change in legal factors or the business climate that could affect the value of the asset, or a significant decline in the observable market value of an asset, among others. The Company’s impairment evaluation is performed at the asset group level or the lowest level for which identified cash flows are largely independent, which the Company has defined as the reporting unit level. If such facts indicate a potential impairment, we assess the recoverability of the asset group by determining if the carrying value of the asset group exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the assets over the remaining economic life of the primary asset of the group. If the recoverability test indicates that the carrying value of the asset group is not recoverable, we will estimate the fair value of the asset group using appropriate valuation methodologies which would typically include an estimate of discounted cash flows, using an appropriate discount rate. Any impairment would be measured by the amount that the carrying values, of such asset groups, exceed their estimated fair value and would be included in operating income (loss) on the consolidated statement of operations. Considerable management judgment is necessary to estimate the fair value of asset groups. Accordingly, actual results could vary significantly from such estimates. We have not identified any circumstances that would warrant an impairment charge for any recorded definite-lived intangibles or other long-term assets on our consolidated balance sheet at December 31, 2023 or 2022 . |
| Foreign Currency Translation and Transaction Gains and Losses | Foreign Currency Translation and Transaction Gains and Losses Our consolidated financial statements are reported in U.S. dollars. Certain of our subsidiaries outside of the U.S. use the local currency as their functional currency and not the U.S. dollar. Therefore assets and liabilities of our foreign subsidiaries are translated at the spot rate in effect at the applicable reporting date, and the consolidated statements of operations are translated at the average exchange rates in effect during the applicable reporting period. The resulting unrealized cumulative translation adjustment is recorded as a component of accumulated other comprehensive income (loss) in stockholders’ equity on our consolidated balance sheet. In addition, our subsidiaries also engage in transactions in currencies other than its functional currency. Transactions denominated in currencies other than the functional currency are recorded based on foreign currency exchange rates at the time such transactions arise. Subsequent changes in foreign currency exchange rates result in transaction gains and losses which are reflected in our consolidated statements of operations as unrealized (based on the applicable period-end exchange rate) or realized upon settlement of the transactions . Accordingly, we have recorded net foreign currency exchange losses of $ 5 million, $ 5 million and $ 4 million, respectively, for the years ended December 31, 2023, 2022 and 2021, in other income (expense), net on our consolidated statements of operations. These amounts also include transaction gains and losses, both realized and unrealized from forward contracts. |
| Derivative Financial Instruments | Derivative Financial Instruments We account for derivative instruments that do not qualify for hedge accounting as either assets or liabilities and carry them at fair value, with any subsequent adjustments to fair value recorded in other income (expense), net on our consolidated statements of operations. Monetary assets and liabilities denominated in a currency other than the functional currency of a given subsidiary are remeasured at spot rates in effect on the balance sheet date with the effects of changes in foreign currency exchange rates reported in other income (expense), net on our consolidated statements of operations. In certain circumstances, we enter into forward contracts to reduce, to the extent practical, our potential exposure to the effects of fluctuating foreign currency exchange rates on our cash flows denominated in foreign currencies. Accordingly, fair value changes in the forward contracts help mitigate the changes in the value of the remeasured assets and liabilities attributable to changes in foreign currency exchange rates, except to the extent of the spot-forward differences. These differences are not expected to be significant due to the short-term nature of the contracts, which to date, have typically had maturities at inception of 90 days or less. The net cash received or paid related to our derivative instruments are classified in other investing activities in our consolidated statements of cash flows. Counterparties to forward contracts consist of major global financial institutions. We monitor our positions and the credit ratings of the counterparties involved and, by policy limits, the amount of credit exposure to any one party. We do not use derivatives for trading or speculative purposes. We did not enter into any cash flow, fair value or net investment hedges during the years ended December 31, 2023, 2022 or 2021. Refer to “Note 3: Financial Instruments and Fair Value Measurements ” for additional information on our derivatives. |
| Fair Value Measurements and Disclosures | Fair Value Measurements and Disclosures We apply fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. We measure assets and liabilities at fair value based on the expected exit price, which is the amount that would be received on the sale of an asset or amount paid to transfer a liability, as the case may be, in an orderly transaction between market participants in the principal or most advantageous market in which we would transact. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability at the measurement date. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. GAAP provides the following hierarchical levels of inputs used to measure fair value: Level 1—Valuations are based on quoted market prices for identical assets and liabilities in active markets. Level 2—Valuations are based on observable inputs other than quoted market prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3—Valuations are based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. |
| Debt Issuance Costs | Debt Issuance Costs We defer costs we incur to issue debt, which are presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, and amortize these costs using the effective interest rate method to interest expense over the term of the debt. We also defer costs we incur to enter into a credit facility or to amend our existing revolving credit facility, which are presented on the consolidated balance sheet as a long-term asset, and amortize these costs using the effective interest rate method to interest expense over the term of the credit facility. |
| Certain Risks and Concentrations | Certain Risks and Concentrations Our business is subject to certain risks and concentrations, including a concentration related to dependence on our relationships with our customers. For the years ended December 31, 2023, 2022 and 2021 , our two most significant travel partners, Expedia (and its subsidiaries) and Booking (and its subsidiaries), each accounted for 10 % or more of our consolidated revenue and together accounted for approximately 25 %, 31 % and 34 % , respectively, of our consolidated revenue, with nearly all of this revenue concentrated in our Brand Tripadvisor segment. Additionally, our business is dependent on relationships with third-party service providers that we rely on to fulfill service obligations to our customers where the Company is the merchant of record, such as our experience operators. However, no one operator’s inventory resulted in more than 10 % of our revenue on a consolidated basis or at a reportable segment level in any period presented. Refer to “Note 18: Segment and Geographic Information ” for information regarding concentrations related to geographic and product revenues and fixed assets by geographic location. As of December 31, 2023 and 2022 , Expedia accounted for approximately 10 % and 19 %, respectively, of our consolidated accounts receivable, net. Financial instruments, which potentially subject us to concentration of credit risk, generally consist, at any point in time, of cash and cash equivalents, corporate debt securities, forward contracts, capped calls, and accounts receivable. We maintain cash balances with financial institutions that are in excess of Federal Deposit Insurance Corporation insurance limits in the U.S. and similar government programs outside the U.S. Our cash and cash equivalents are generally composed of available on demand bank deposits or term deposits with several major global financial institutions, as well as money market funds, primarily denominated in U.S. dollars, and to a lesser extent Euros, British pounds, and Australian dollars. We may invest in highly-rated corporate debt securities, and our investment policy limits the amount of credit exposure to any one issuer, industry group and currency. Our credit risk related to corporate debt securities is also mitigated by the relatively short maturity period required by our investment policy. Forward contracts and capped calls are transacted with major international financial institutions with high credit standings. Forward contracts, which, to date, have typically had maturities of less than 90 days , also mitigate risk. Our overall credit risk related to accounts receivable is mitigated by the relatively short collection period. |
| Contingent Liabilities | Contingent Liabilities Periodically, we review the status of all significant outstanding matters to assess any potential financial exposure. When (i) it is probable that an asset has been impaired or a liability has been incurred; and (ii) the amount of the loss can be reasonably estimated, we record the estimated loss in our consolidated statement of operations. We provide disclosure in the notes to the consolidated financial statements for loss contingencies that do not meet both these conditions if there is a reasonable possibility that a loss may have been incurred that would be material to the consolidated financial statements. Significant judgment may be required to determine the probability that a liability has been incurred and whether such liability is reasonably estimable. We base accruals made on the best information available at the time which can be highly subjective. The final outcome of these matters could vary significantly from the amounts included in the accompanying consolidated financial statements. |
| Treasury Stock | Treasury Stock Shares of our common stock repurchased, including incremental direct costs to purchase treasury stock, including excise tax, are recorded at cost as t reasury stock and result in the reduction of stockholders' equity on our consolidated balance sheet. We may reissue these treasury shares. When treasury shares are reissued, we use the average cost method for determining the cost of reissued shares. If the issuance price is higher than the cost, the excess of the issuance price over the cost is credited to additional paid-in-capital. If the issuance price is lower than the cost, the difference is first charged against any credit balance in additional paid-in-capital from the previous issuances of treasury stock and any remaining balance is charged to retained earnings. |
| Earnings Per Share (“EPS”) | Earnings Per Share (“EPS”) Basic Earnings Per Share Attributable to Common Stockholders We compute basic earnings per share, or Basic EPS, by dividing net income (loss) by the weighted average number of common shares outstanding during the period. We compute the weighted average number of common shares outstanding during the reporting period using the total of common stock and Class B common stock outstanding as of the last day of the previous year end reporting period plus the weighted average of any additional shares issued and outstanding less the weighted average of any common shares repurchased during the reporting period. Diluted Earnings Per Share Attributable to Common Stockholders Diluted earnings per share, or Diluted EPS, includes the potential dilution of common equivalent shares outstanding that could occur from stock-based awards and other stock-based commitments using the treasury stock method. We compute Diluted EPS by dividing net income (loss) by the sum of the weighted average number of common and common equivalent shares outstanding during the period. We compute the weighted average number of common and common equivalent shares outstanding during the period using the sum of (i) the number of shares of common stock and Class B common stock used in the Basic EPS calculation as indicated above; (ii) if dilutive, the incremental weighted average common stock that we would issue upon the assumed exercise of outstanding common equivalent shares, primarily related to stock options and the vesting of restricted stock units using the treasury stock method; and (iii) if dilutive, performance-based and market-based awards based on the number of shares that would be issuable as of the end of the reporting period assuming the end of the reporting period was also the end of the contingency period. Under the treasury stock method, the assumed proceeds calculation includes the actual proceeds to be received from the employee upon exercise of outstanding equity awards and the average unrecognized compensation cost during the period. The treasury stock method assumes that a company uses the proceeds from the exercise of an equity award to repurchase common stock at the average market price for the reporting period. In periods of net income, shares of our common stock subject to the potential conversion of the 2026 Senior Notes outstanding during the period is also included in our weighted average number of shares outstanding used to calculate Diluted EPS using the if-converted method under GAAP, as share settlement is presumed. When convertible notes are dilutive, interest expense, net of tax, is added back to net income attributable to common stockholders to calculate Diluted EPS. Capped Calls are excluded from the calculation of Diluted EPS, as they would be antidilutive. However, upon conversion of the 2026 Senior Notes, unless the market price of our common stock exceeds the cap price, an exercise of the Capped Calls would generally offset any dilution from the 2026 Senior Notes from the conversion price up to the cap price. As of December 31, 2023, 2022, and 2021 , the market price of a share of our common stock did not exceed the $ 107.36 cap price. Refer to “Note 8: Debt ” for further information regarding our 2026 Senior Notes and Capped Calls. In periods of a net loss, common equivalent shares are excluded from the calculation of Diluted EPS as their inclusion would have an antidilutive effect. Accordingly, for periods in which we report a net loss, such as for the year ended December 31, 2021, Diluted EPS is the same as Basic EPS, since dilutive common equivalent shares are not assumed to have been issued if their effect is antidilutive. |
| Recently Adopted Accounting Pronouncements | New Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance requiring entities to provide additional information in the income tax rate reconciliation and additional disclosures about income taxes paid. The new accounting guidance requires entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if the items meet a quantitative threshold. This guidance is effective for annual periods beginning after December 15, 2024, and should be applied prospectively, but entities have the option to apply it retrospectively for each period presented. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. In November 2023, the FASB issued new accounting guidance which expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM") and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This guidance is effective for annual periods beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024, with early adoption permitted, including adoption in any interim period. We are currently considering our timing of adoption and are in the process of evaluating the impact of adopting these newly issued accounting rules on our consolidated financial statements and related disclosures. |
